It has come to my attention that the amount of reputation awarded for questions can be adjusted on a per-site basis. For example, Stack Apps awards +10 reputation for question upvotes. As you probably already know, we currently award +5 reputation, as do most Stack Exchange sites, including Stack Overflow.
The lower reputation amount makes sense in the context of a Q&A format since it takes less effort to ask a question than it does to answer it. However, we're a little different in that quality challenges can be far more difficult to create than quality answers.
Thus I propose that we raise the amount of reputation we award on questions from +5 to +10.
This was proposed 4 years ago and was deemed to be a good idea but no action was taken. It was also addressed on Meta.SE and was met with hesitation there. I think it would be worth a discussion now on our site, particularly since it has become apparent that the modification is possible.
Note that the change would apply retroactively; reputation would be recalculated for all users who have ever posted a question on this site. That is, in the system, it will be like the user earned the reputation the day the upvote was given, even if it was in the past. The 200 reputation per day cap would still apply on those days though. For some users, this may result in many thousands of reputation points gained.
Note: Due to near unanimous support for this proposal, I've converted this from a community discussion to a formal feature request that will hopefully be addressed by Stack Exchange.
